Rashi: The Navi laments over himself ? woe to me that I was appointed Navi at this time, that there are not Tzadikim in the generation!

Radak citing his brother R. Moshe: It is an expression of wailing. The Aleph is in place of a Yud, like Yishai and Ishai (refer to 6:10:1:1). Woe to me for the evils of Yisrael ? they did not heed my rebuke, and woe to me for their afflictions - Hashem will punish them.

Rashi, Targum Yonasan: These are Sofei Te'enim [figs left on the tree at the end of harvest, for they never ripen], which are bad. Rashi ? Aspei is not a verb like Yoshev or Omer. It is Mif'al (a noun), like "Osef ha'Chasil" (Yeshayah 33:4).

Radak: I remained a small amount after they reaped and gathered the summer fruits.

Malbim: His generation is compared to a vineyard of vines or fig trees. Those early to ripen were gathered;

Rashi citing Targum Yonasan: Like Olelin (deficient clusters) after the harvest.

Rashi citing Targum Yonasan: There is no man with good deeds.

Radak: I do not find on the vine one cluster to eat ? all were harvested. I.e. there is not one Chasid and straight person that I will learn from his deeds.

Rashi: A good fig that ripens in its time, like the Targum 'good, the desire of my Nefesh.'

Radak: If the Chasidim and straight ceased, my Nefesh desires that one of the generation will teach the ways of Chasidim and the straight; Bikurah is a Mashal for this.
